Nano-sponge/melamine foam, also known as melamine foam, is inherently flame retardant, high temperature stable and flexible. The length-to-diameter ratio of the grid is about 10 to 20, and its extremely high opening ratio characteristics (the opening ratio of Sisian melamine foam with a density of 6kg/M3 is over 97%). Sound waves can easily and efficiently enter the deep layers of the foam and transform into vibrations of the mesh that can be consumed and absorbed, and effectively eliminate the reflected waves, especially the absorption characteristics of low frequency noise. The absorption characteristics of low frequency noise exhibited by Xiamen Sihang melamine foam have attracted great interest from experts in the acoustic field and have begun to be used more widely.

Nanosponge has a very high opening ratio

l 97% open porosity, completely connected by three-dimensional mesh fiber filaments → outstanding sound absorption effect;

l Very low density, 8.5 kg / m3 → save energy;

l The flame retardancy of melamine foam itself → no need to add flame retardant to reach the B1 standard, no dripping, no toxic fumes;

l High temperature stability of melamine foam → long-term working temperature -180 °C - 200 °C;

l Chemical stability → strong alkali resistance, weak acid.

 High-decibel noise in industrial and manufacturing environments not only reduces productivity, but also threatens workers' health. Studies have shown that exposure to high noise environments can lead to stress and fatigue, which can lead to work-related injuries or hearing loss.

Work environments that are subject to high-intensity noise (such as heavy construction machinery working noise and metal processing plants and other confusing people's voices) can be restored to acceptable levels by installing nano-sponge/melamine foam sound absorbing panels. . Nano Sponge/Milamine Foam Wall Panels and Refractive Plates reduce and control noise and reverberation in factories, assembly plants and other industrial applications by blocking and filtering sound waves.

Nanosponge/melamine foam can solve invisible industrial noise before it becomes a problem, and has helped countless companies protect the health of their employees and save on expensive insurance claims.

The extremely high opening porosity of the nanosponge allows sound waves to be easily absorbed and absorbed into the deep layers of the foam. The sheet of nano-sponge can be made into a embossed acoustical ceiling and coil by hot pressing, while the surface strength is improved. The noise reduction of nano-sponges in cars will greatly improve the experience of drivers and occupants. At the same time, China's urban traffic construction has entered a stage of rapid development. The problem of road noise disturbance has attracted wide attention. Nano-sponge has great application potential in noise reduction and noise reduction of expressways. Architectural engineering and acoustic experts have fully affirmed the sound absorption performance of the new material.

Nano-sponge has a unique combination of sound absorption, heat insulation, flame retardancy, high temperature resistance and light weight. Widely used in the fields of architectural decoration, transportation vehicles, watercraft, aerospace, electromechanical equipment, industrial sound absorption and insulation. Nano-sponges make it possible to improve the noise immunity, safety and energy saving of vehicles. In addition, it is also widely used in the noise treatment of boiler rooms, compressor rooms, pumping stations, stamping workshops and blowers. It will gradually replace the commonly used sound-absorbing and heat-insulating materials such as glass wool, felt, ordinary foam, polyurethane, asbestos, polystyrene and polyethylene, and become a new sound-absorbing and heat-insulating product that has attracted attention in the market.
